Title: Mathematically inspired musical scales
Abstract: We review some basics of "musical physics" from Pythagoras to modern times, and then examine variations on these ideas whereby we can build nonstandard musical scales inspired by the elementary functions of mathematics. We then show how to build an infinite family of musical scales for which Wendy Carlos's alpha, beta, and gamma scales are special cases. Some of this work is ongoing and joint with Robert Schneider, frontman for the indie rock band The Apples in Stereo, and Assistant Professor of Mathematics at Michigan Technological University.

Title: Mechanical proofs of partition identities through atomic relations
Abstract: Integer partition and q-series sum-to-product identities, such as the Rogers-Ramanujan identities, lie at the intersection of combinatorics, number theory, and the representation theory of affine Lie algebras. This talk will focus on the method of atomic relations, which has been developed by Shashank Kanade and the author in recent years as a way to prove these identities. In some cases, computer output from this method can guide human-constructed proofs, while in other cases, our proofs are totally computer-generated. Applications of this method to problems involving cylindric partitions and colored partitions will also be discussed.
